cans containing milk out of the same batch "withthe same number, so thatif, upon testing one or more cans of the batchit shall be discoveredthat they are unmarketable,"th'e entire batch can be separated"and'destroyed. The marking of the cans has heretofore been done bymeans of a rubber stamp, or" other unsatisfactory method, requiringconsiderable time and labor, and the purposeof the present device is tohave the cans successively marked by simple. and effective mechanism, asthe milk is passingthrough the canning process. This process consists inpassing a successionof cans along a table at certain points of whichsaid cans are filled and sealed, after which they are delivered to thelabeling machine. The movement of the cans through the main machine-isnecessarily of an intermittent nature, and the hereinafter describedmarking devices'are associated with the main machine, and theiroperation so timed, as to cause the cans tobe successively marked withthedesired 111mlber at the instant whensuch cans are at rest.

The several featuresand advantages of the invention will be more fullyapprehended from the following specification, reference being had to thedrawings accompanying the same, in which: j

Figure l is aplan view "or my invention, with a fragment of the machinewith which it is associated, and some ofthe gear devices indicated inbroken lines.

Fig. 3 is an end view of the type-holder 35. Fig. 4: is aptop viewof oneof the arms 33, and

Fig. 5 is a side view thereof. U The main table of the machine isindicated at 6, such table being of circular form, and supported andarranged so as to receive an intermittent rotary movement. Supfixed tothe upper face of thetable 7. ing through the shaft 10, so as tohave'free ported adjacent to the table 6 isan auxiliary table 7,'to thelower face of which is fixed a bracket 8','upon which is supported agear wheel 9. Connected with thewheel 9, soas to rotate therewith, is ahollow shaft -10,extending upwardly intoa boXin 11,

ass-

vertical movement therein, is a spindle-12,

rotatable with the shaft 10by means ofa pair of rollers 13 engaged inslots'lin the upper end of said shaft. The lower end of the spindle 12isthrea ded and provided with a thumb-turn 15, between which and thebracket 8 is interposed a'coiled sprin 16, W is to force the spindle '12downwardly.

the tendency of which Held rigidly in the boxingl l is a sleeve 17,providedat'its upper end with collar '18, in which is 'arecess 19,havingan inclined face 20. Fixed to the spindle 12 abovethe collar 18 isa collarl2l, provided with a .lug'22, of similar shape and size to therecess 19. The collar 18is provided at the opposite side from the recess19 with another recess similar thereto. This results in the collar 21and spindle 12 being drawn downwardly twicein each rotation of suchspindle." p f Movement is imparted to the gearwheel 9 by means of anidler gear 23, supported be' 'neath the table 7, said idlergear beingactuated bya gear wheel 25011 a shaft 26, On the same shaft is agear-wheel 27,111 mesh with a large gear wheel 28fsupported be- Saidlast named gear-wheel is commonly found in use with machines containingsuch tables. g

the. table 6 and gear 28 is communicated to the shaft 10, to impartthereto a half 'rota-* tion upon each movement of the table 6. Thismovement is also communicated 'to the "spindle 12, through-*the rollers13 and slots 14. 4

Fixed to the upper end of the spindle 12 is a head 29,"provided with apair of radial projections 30, having heads- 31 at their outer ends.Saidprojections and'heads' are provided-with recesses 32,in which arms331 are pivoted at their inner ends, so that said arms will swingvertically. At the outer ends of the. arms ,33 are pins 34;, upon whichare supported type-holders 35,recessed .at' their lower ends so as toreceive type 36,

.arrest oi' the sp ndle and parts attached provided with desiredcharacters. The

parts 35 are held in place by means oi,

latches 35, engaging notches in the ends of the pins 34. The arms 33 areheld yieldably in elevated position by means of springs 38, secured tothe head 29, and bearing against the lower edges of said arms. j Securedto the upper edges of the arms 38 are springs 39, ending in plates 40,which have a resilivent bearing upon the upper faces of the type-holders8 5, permitting a limited rockingmovement to said parts.

Mounted on oneside of the table is a boxing 41, in which is rotatable apin 42,

on the .upperend of which is a plate 43,

provided with an inking pad 44. Intermittent'rotationis imparted to thepin 42 by vmeans of a pulley 45 on the lower end there.

of, actuated'by abelt 46 from a pulley 47 on the shaft 10.

In operation, a series oi cans is being -moved along the edge of thetable 6, in-the direction indicated by the arrow. The spindle 12 isgiven a rotation opposite thereto, causing one or other'of the arms 30to 'move along for a little distance ith the table 6. When themoveinentof; such table is interrupted for an instant,the type-holder .isimmediately above one ofthe cans thereon. Atthe same time the cam 22drops into one of the recesses 19, letting the spindle 12 and mechanismsupported thereby move downwardly with considerable force, caused bygravity and the action of the spring 16.

This movement is suddenly interrupted when the collar 21 comes incontact with the collar 18. At thistime the marking device whichprojects over the can is'brought into proximity therewith, and the arresulting froni'the downward movement and sudden thereto, forces themarking head and supporting arm downwardly against the action of thespring 38, causing an impact of the 45,

type against the endoi the can. The spring 38 at once returns such'partstov their former positions, and the movement of the cans proceeds. Thetiming of the-parts is such that the arms 30 are alternately turned intoposition above the table 6. The inking pad 44 is so positioned that whenthe marking device at the end of one of the arms 30 is operating upon acan,'the type of the other 'one is being provided with a fresh supply ofink. In inking the type the operation is similar to that of marking thecans, the type being brought into proximity to the pad, and then forceddownwardly by the sudden jar imparted thereto. In case the top of a canis not exactly level, the type-holder is permitted to rock suiiicientlyto bring the type into a proper position for printing thereon. f

The position of the inking devices is such that the type will alwayscome in contact porting member; means for holding said supporting memberwith said marking device in an inoperative position; means for suddenlyreleasing the same, so as to bring said marking device into an operativeposition,-with a sudden interruption at the-end thereof, giving anindependent movement to said marking device; and means for suitablyrotating said'first-named member.
